Recycling a PC Power supply
« on: January 11, 2015, 10:30:41 AM »
Has anyone had any success in recycling a desktop power supply for use?

There is lots of 12v cables coming off of this thing as well as the main one for the motherboard.

However; the ones for the devices (CD ROM's) etc do not get power until the system has been powered on.. How does one trick it to turn it on to get power out these cables?

That is awesome, however; my solder skills are not adequate enough to make a board like this work. I would be worried about it failing and burning up something small or big.

I'd gladly pay someone to make them with the BOM installed :)

I haven't used the previously recommended item, and this one either :
http://www.diyledexpress.com/index.php?main_page=product_info&cPath=51&products_id=246

...but it seems to be trying to accomplish similar things.  This one seems to target 5v over 12v.  The one mentioned earlier seems to be 12v only, if I'm understanding it correctly.

AMAZING!!! yes this is to just test mainly. and then get things up and running with regular / enclosed power supplies.

THANKS! I really appreciate the digging the sites!

There is 5v and 12v on the Falcon Adapter although there are more 12 connections.  I bought about 30 of those along with my model railroad friends and we use them for lighting effects on the railroad layouts.  It is a pretty easy and quick solder job.

I run a lot of my show on PC power supplies. Don't discount using them for some of your projects. The best ones are the single rail supplies, this info is usually noted on the supply and means there is technically only a single source of the +12 power.

Something like this works nicely for 12v controllers like the F16.

It is a fairly easy mod to do, and for $20 a power supply, it's good bang for your buck as it puts out 30A at 12V. I have several similar supplies from different DL380s i've salvaged from work in the past.

Said the same things myself...  Get a decent iron and go fer it!  Seriously, you are missing out on one of the best things in blinky.  At least in DIY blinky that is!

I'm with you Sam.  I found that between a good station (http://www.amazon.ca/Weller-WES51-Analog-Soldering-Station/dp/B000BRC2XU)  and the solder, a good tip, a clean desk, good light  and reading a couple quick guides to solder, it's been really easy to do.

Rewind the clock a few years -  I tried to install a mod on an xbox way back when (to play backed up games my kids already owned, but they were terrible at scratching disks) and needed to solder something on the motherboard - lets just say  it went bad. very bad.

Then when I saw RJs stuff a few years back, I said how much money am I going to throw out the window this time - well I got the courage to get in the first coop I could (it was the lynx express) and invested in some good tools and was pleasantly surprised at the success. I don't touch that surface mount  and desolder (if that's a word) components - but putting a board together isn't that bad.

I was able to get the power adapter on my EDM RDS after 3 tries! that is a lot of time invested to make it work properly if i have to do things 3x!. When playing with these ..

If at first you don't succeed, try, try again.

If you believe you can't do it you will be correct you can't.

Be sure to get a good solder sucker, for those oops....... It is one of the best solder tools you can have. LOL

Oh and also use as small diameter solder you can get, only use the big stuff for large things like soldering 12 or 14 ga wire together.

You know soldering wires together is a good way to practice connecting things without risking too much $$$.

Also joining wires is a big part of this hobby so a good thing to be efficient at.

I know. I have just never really had to do it. This year i had some RGB.. and used crimp caps to get by.
Last summer, some major events precluded me from focusing many hours to do a good job on the installation.

This year is different!
Thanks for the encouragement!

I just recycled two PC power supplies.   They are running ae Lynx cards to bench test pixela and a few are in  the yard running elements.  Cheap amd easy
  There are multiple sites and YouTube videos to show you how  to do it.
